Display panel having minimum distance from spacer to adjacent active display region within preset range and display device

Abstract

A display panel and a display device are provided. The display panel comprises a first substrate (1) and a second substrate (2) provided opposite to each other, and a spacer (101) provided between the first substrate (1) and the second substrate (2). The spacer (101) is covered with an alignment film (4), both the first substrate (1) and the second substrate (2) includes an active display region (102) and a non-display region (103), the spacer (101) is provided in the non-display region (103) of the first substrate (1) and the non-display region (103) of the second substrate (2). A minimum distance value from an edge of the spacer (101), which is an edge closest to the active display region (102) along a rubbing direction of the alignment film (4), to the active display region (102) along the rubbing direction of the alignment film (4) is within a preset range for avoiding light leakage caused by the spacer. In the case that an aperture ratio is ensured, light leakage due to insufficient strength of rubbing the alignment film (4) in a partial region caused by shielding of the spacer (101) is avoided.
